KFC previously had an item on the menu called popcorn chicken,
but that was discontinued in 2011.

Those who enjoy fried food will love this poppable, snackable
take on chicken nuggets.

KFC advertised the nuggets as "100% white meat. The way
nuggets should be."

The company also wrote:

"KFC Popcorn Nuggets are 100% white meat, extra crispy, and
made from the world’s best chicken. Grab them on the go or add
them as a side to your next meal. Either way, you won’t look at
nuggets the same ever again."
